“Let me tell you, you take on the intelligence community, they have six ways from Sunday to get back at you. So, even for a practical, supposedly hard-nosed businessman, he is being really dumb to do this,” Schumer said in a Jan. 3 MSNBC interview.

Asked what intel officials could do to Trump, Schumer said, “I don’t know, but from what I am told, they are very upset with how he has treated them and talked about them,”

Schumer was referring to Trump last week questioning the legitimacy of the Russian hacking probe — before Tuesday’s bombshell reports that an intel dossier was prepared of unverified claims that Russia had compiled compromising and salacious dirt on Trump.

Ramping up his criticism of intel officials, Trump on Wednesday called the dossier on the unsubstantiated claims a “tremendous blot” on the intellegigence agencies.

“It is a disservice that information would be leaked. It’s crap. It’s all fake news. It didn’t happen,” Trump said at press conference at Trump Tower.
